    +1 on sort the blend motors. Step-1 try moving them to 50% with Nanocom, and also try the Calibration option. Essentially you have two issues, i.e. the blend & distribution motors, plus probably no gas causing the compressor clutch error.

    Easy enough to access. Just unbolt the mounts & turn it over. The EAS 12V is on C174. Plenty of ignition switched feeds under there as well.

    Are the Sensor voltages going up & down ? Could also be the sensor connectors either side of the block. They do tend to gather oil down there.

    . . . . . and one other point. If you do this, make sure you wait for the BECM & EAS to go to sleep before doing any wiring. If you interupt the EAS before it sleeps, you can end up with odd behaviour where the car drops to access every time...

    The pressure switch is always open, so it looks like the pump never achieves required pressure. If the system isn't leaking then the pump needs a refurb again. TBH, I have found the refurb kits never seem to last as long as they used to (both...

    Read the Nanocom guides first, so you know what the menus do for each ECU. Also check the seat fuses. With Ignition on, you need to read the EMS code, and write it down. Then with Ignition off, write that into the Immobilisation Code box in...

    Does the pressure switch definitely change state ? Another path for tank leak is via NRV-1 & out the exhaust silencer when the pump is off & diaphragm open.

    You can't change the setting because it's an input. The switch on the pedal frame has two contacts in it. Onbe is normall closed & the other normally open. Therefore both toggle on Inputs screen on the Nanocom when you press the pedal.
